mysql - Combine Blackboard 9.1.13 console SQL queries -


how combine these 2 sql blackboard queries single query ("and") run on console list testrole1 testrole2 secondary role?

select user_id users institution_roles_pk1 = (select pk1 institution_roles role_name = 'testrole1');

select user_id users pk1 in (select users_pk1 user_roles institution_roles_pk1 = (select pk1 institution_roles role_name = 'testrole2'));

you not need use user_roles table other 2 tables have fields need query work:

select u.user_id users u, institution_roles ir u.institution_roles_pk1 = ir.pk1 , ir.role_name = 'testrole1' , ir.role_name = 'testrole2';

this give list of users have both these institutional roles.
